About the Vaillant ecoFIT Pure 615 System Boiler
A system boiler provides central heating and works with a separate hot water cylinder to store domestic hot water. Unlike a combi boiler, which heats water on demand, a system boiler can supply hot water from a suitably sized cylinder, helping meet the needs of households that use several taps or showers.
The Vaillant ecoFIT Pure 615 incorporates a built-in pump and expansion vessel, reducing the need for certain external system components. Its aluminium heat exchanger and automatic purging assistant are designed to support the boiler's operation, while the compact casing can help when planning a space-conscious installation.
Actual heating performance and suitability depend on the property's heat loss, the hot water cylinder, system design and controls. A qualified heating professional should confirm the correct boiler output and compatibility before purchase.
